X1= -3/2
X2= 0
F(x)=4x^2+6x
To find X-intercept/zero, substitute f(x)=0
0=4x^2+6x
Move the constant to the right
4x^2+6x=0
Factor out 2x from the expression
2x(2x+3)=0
Divide both sides of the equation
2x(2x+3)/2=0/2
X(2x+3)=0
When the product of factors equals 0, at least one factor is 0.
X=0
2x+3=0
Next you solve for X by moving the constant to the right
2x=-3
Then divide both sides by 2
X=-3/2
Hope this answers your question.
The equation would have to be set up as 4b - 4 = 10.36. This is because you’re buying 4 boxes of fruit loops, and $1 taken off each box is $4 total for all four boxes.
Answer:5
Step-by-step explanation:
f(4)= ((1/2)*4)+3= 2+3=5
From the given recurrence, it follows that
and so on down to the first term,
(Notice how the exponent on the 2 and the subscript of <em>a</em> in the first term add up to <em>n</em> + 1.)
Denote the remaining sum by <em>S</em> ; then
Multiply both sides by 2 :
Subtract 2<em>S</em> from <em>S</em> to get
So, we end up with
Answer:
82.5 km
Step-by-step explanation:
Given:
Cross-multiply.
2x = 11(15)
Divide both sides by 2 and solve for x.
x = 82.5 km
